摘要：
An image forming apparatus includes: a photoconductor that rotates about a first rotation axis; and a charging roller that rotates about a second rotation axis which is parallel to the first rotation axis, wherein the charging roller includes a conductive roller portion that extends in parallel with the first rotation axis and contains an ion-conductive agent, a flange portion that is provided on an outer peripheral surface of the conductive roller portion further to the outside than an image forming area of the photoconductor in the second rotation axis direction so as to protrude outward from the outer peripheral surface in the radial direction of the conductive roller portion into a flange shape, and an insulating elastic layer that coats the outer peripheral surface of the flange portion and has an elasticity higher than that of a photoconductive surface of the photoconductor.
